Option B is the correct answer.
Though the handwriting isn't properly understood, yet I was able to see some of the writings.
Passive voice refers to the statement or sentence which consists of a subject that is acted upon by other performer of the verb. In other words, the subject of the clause actually receives the action of the verb.
So, from this excerpt, "Trees" (what I am seeing written there) is the subject that is receiving the action.
In active voice, the subject actually performs the action while in passive voice, the subject receives the action.
